Manufacturer's Description from SPL

With Gemini, M/S processing enters the SPL Mastering series. Gemini is an M/S Encoder and Decoder. Mid signals (voice, snare, bass …) can clearly be seperated from side signals (guitar, spatial sounds, cymbals …) and can individually be processed. When working on the sum signal, M/S coding often is the best way to specifically get access to individual elements within a mix. 


Gemini also provides the possibility to work on the stereo panorama. With the Balance control you can position the mid signal within the stereo panorama. With the Trim control, you can adjust the level of the mid signal in relation to the side signal. In connection with the Stereo Width control, the mixing ratio of both channels can be adjusted. 


An Elliptical Filter, which can cut low frequency ratios of the side band is also provided.
